Patent JP-2001296966-A (JP)
Title: Input device
Inventor: SUZUKI KATSUTOSHI
IPC: G06F3/033
Filed: 2000-04-17
Abstract: PROBLEM TO BE SOLVED: To solve such a problem that the detecting precision of the operating angle and the operating direction of an operation body cannot be improved in particular in a conventional input/output device. SOLUTION: When the operation body is rotated, a movable member 8 fixed to this is rotated together. When the rotation angle is 0 deg., movable electrodes 9a, 9b, 9c and 9d are respectively overlapped on detection electrodes kc1, kc2, kc3 and kc4 (movable electrodes kc), thereby capacitance during this state is detected as a maximum value. When the member 8 is rotated by 22.5 deg. e.g. counterclockwise next, the respective movable electrodes are respectively overlapped on the detection electrodes kd1, kd2, kd3 and kd4 (movable electrodes kd), thereby capacitance between the electrodes kd and an opposed electrode is detected as a maximum value. Thus, by detecting the capacitance during rotation continuously in a prescribed sampling time, the operating angle and the operating direction of the operation body can be detected.
